High-speed railway (HSR) station areas are expected to benefit urban environments, not simply as transportation or economic hubs but also as urban places contributing to living quality. However, the relationship between HSR and place quality has not received systematic attention, despite the evolution of urban planning paradigms toward a clearer focus on quality of life. We have reviewed 44 academic articles written between 1996 and 2019 and analyzed concepts of place quality spanning the disciplines of urban design, urban planning, and urban economics. We identified three dimensions commonly associated with quality of place: a spatial dimension associated with aesthetic qualities of urban spaces; a socio-cultural dimension associated with experienced “sense of place”; and an economic dimension associated with the agglomeration of economic activities. Then we worked out these three dimensions in the context of HSR station areas and attributed features accordingly. We concluded that the economic dimension far outweighs the others in academic debates, with dominant theories being primarily concerned with land use, accessibility, and economic performance. Studies from the urban design field have tackled the spatial elements of place quality and showed a strong correlation with economic dimension. However, the literature remains insufficiently developed when it comes to addressing user experience and “sense of place.”
高铁站点区域不仅作为交通或经济中心,而且作为提高生活质量的城市场所,预计将有利于城市环境。然而,尽管城市规划范式朝着更明确地关注生活质量的方向发展,高铁与场所质量之间的关系却没有得到系统的关注。我们回顾了1996年至2019年间撰写的44篇学术文章,并分析了城市设计、城市规划和城市经济学等学科的场所质量概念。我们确定了通常与场所质量相关的三个维度:与城市空间美学质量相关的空间维度;与体验“地方感”相关的社会文化层面;以及与经济活动集聚相关的经济维度。然后在高铁站点区域的背景下计算出这三个维度,并对其特征进行属性化。我们得出的结论是,在学术辩论中,经济维度远远超过其他维度,主导理论主要关注土地利用、可达性和经济绩效。城市设计领域的研究已经解决了场所质量的空间要素,并显示出与经济维度的强烈相关性。然而,当涉及到用户体验和“地点感”时,文献仍然不够发达。

The relationship between the built environment and walking behavior has been explored extensively. However, little research has been done to either differentiate between walking for transport and walking as activity or that applies urban design tools to walkability improvement based on environment-walking associations. Therefore, this study constructed perceived environment walkability factors to replace unidentified physical environments that varied among individuals and examined their associations with walking to a destination (purposive walking) and walking as activity (discursive walking), using factor analysis and structural equation modeling. Results suggest that residential density, land-use mix diversity, and pedestrian/traffic safety were associated with purposive walking while aesthetics and crime safety were associated with discursive walking. Land-use mix access and street connectivity were common correlates of both walking patterns. This study also explored how to apply urban design tools, including land-use plans, zoning control, and urban design guidelines, to shape a walkable environment based on the environment-walking associations.
建筑环境与步行行为之间的关系已经得到了广泛的探索。然而,很少有研究将步行作为交通工具和步行作为活动进行区分,或者将城市设计工具应用于基于环境步行协会的步行能力改善。因此,本研究构建了感知环境可步行性因素,以取代个体之间变化的未识别物理环境,并使用因素分析和结构方程建模,检验了它们与步行到目的地(目的性步行)和步行作为活动(话语性步行)的关联。结果表明,住宅密度、土地利用组合多样性和行人/交通安全与有目的的步行有关,而美学和犯罪安全与散漫的步行有关。土地利用混合通道和街道连通性是两种步行模式的共同相关性。本研究还探讨了如何应用城市设计工具,包括土地使用规划、分区控制和城市设计指南,以基于环境步行协会来塑造可步行的环境。

This paper explores relationships between commuting times, job accessibility, and commuting satisfaction based on a large-scale survey applied in the Greater London Area (GLA), the municipality of São Paulo (MSP) and the Dutch Randstad (NLR). Potential accessibility to jobs is estimated under 3 different scenarios: reported actual commuting times (ACT), ideal commuting times (ICT), and maximum willingness to commute (MCT). In addition, binary logistic regression models, estimated using generalized linear modeling (GLM), are performed to assess the impact of these temporal preferences on the likelihood of being satisfied with commuting. As expected, ideal and maximum commuting preferences strongly impact the volume and spatial distribution of the measured accessibility to jobs. In the selected case studies, estimated ICT-based job accessibility significantly decreases total measured accessibility (60 to 100 percent), with those living in the lowest accessibility zones impacted most. Furthermore, although specific results varied between regions, the overall findings show an association between ACT and satisfaction. Likewise, commuting mode is found to be a strong predictor of travel satisfaction. Those actively traveling in all three metropolitan regions tend to be more satisfied with their commutes. Potential job accessibility is found to be only weakly associated with travel satisfaction.
本文基于在大伦敦地区(GLA)、圣保罗市(MSP)和荷兰兰德斯塔德市(NLR)进行的一项大规模调查,探讨了通勤时间、工作可及性和通勤满意度之间的关系。在三种不同的情况下估计了潜在的就业机会:报告的实际通勤时间(ACT)、理想通勤时间(ICT)和最大通勤意愿(MCT)。此外,还使用广义线性模型(GLM)估计了二元逻辑回归模型,以评估这些时间偏好对通勤满意度的影响。正如预期的那样,理想和最大通勤偏好强烈影响所测量的就业机会的数量和空间分布。在选定的案例研究中,基于信息和通信技术的工作可及性估计大大降低了测量的总可及性(60%至100%),其中生活在可及性最低地区的人受到的影响最大。此外,尽管各地区的具体结果各不相同,但总体研究结果显示ACT与满意度之间存在关联。同样,通勤模式被发现是旅行满意度的有力预测因素。那些在这三个大都市地区积极旅行的人往往对通勤更满意。研究发现,潜在的工作可及性与旅行满意度的相关性很弱。

As a sustainable mode of travel, walking for transportation has multiple environmental, social, and health-related benefits. In existing studies, however, such walking has rarely been differentiated between commuting and non-commuting trips. Using multilevel zero-inflated negative binomial regression and multilevel Tobit regression models, this study empirically examines the frequency and duration of commuting and non-commuting walking and their correlates in Xiamen, China. It finds that (1) non-commuting walking, on average, has a higher frequency and longer duration than commuting walking; (2) most socio-demographic variables are significant predictors, and age, occupation, and family size have opposite-direction effects on commuting and non-commuting walking; and (3) different sets of built environment variables are correlated with commuting and non-commuting walking, and the built environment collectively influences the latter more significantly than the former. The findings provide useful references for customized interventions concerning promoting commuting and non-commuting walking.
作为一种可持续的出行方式,步行交通具有多种环境、社会和健康益处。然而,在现有的研究中,这种步行很少区分通勤和非通勤旅行。本研究采用多水平零膨胀负二项回归和多水平托比特回归模型,实证检验了厦门市通勤和非通勤步行的频率和持续时间及其相关性。研究发现:(1)非通勤步行平均比通勤步行频率更高,持续时间更长;(2) 大多数社会人口学变量是显著的预测因素,年龄、职业和家庭规模对通勤和非通勤步行具有相反的方向影响;(3)不同的建筑环境变量集与通勤和非通勤步行相关,建筑环境对后者的总体影响大于前者。研究结果为促进通勤和非通勤步行的定制干预措施提供了有用的参考。

Viewpoint: Turning streets into housing 观点:把街道变成住房
IF 1.9 4区 工程技术 Q4 TRANSPORTATION Pub Date : 2021-10-06 DOI: 10.5198/jtlu.2021.2020

I argue that wide residential streets in US cities are both a contributor to homelessness and a potential strategy to provide more affordable housing. In residential neighborhoods, subdivision ordinances typically set binding standards for street width, far in excess of what is economically optimal or what private developers and residents would likely prefer. These street width standards are one contributor to high housing costs and supply restrictions, which exacerbate the housing affordability crisis in high-cost cities. Planning for autonomous vehicles highlights the overprovision of streets in urban areas. Because they can evade municipal anti-camping restrictions that restrict the use of streets by unhoused people, autonomous camper vans have the ability to blur the distinction between land for housing and land for streets. I propose two strategies through which excess street space can accommodate housing in a formalized way. First, cities could permit camper van parking on the right-of-way, analogous to liveaboard canal boats that provide housing options in some UK cities. Second, extending private residential lots into the right-of-way would create space for front-yard accessory dwelling units.
我认为,美国城市宽阔的住宅街道既是造成无家可归的原因,也是提供更多负担得起的住房的潜在策略。在住宅区,分区条例通常为街道宽度设定有约束力的标准,远远超过经济最佳或私人开发商和居民可能喜欢的标准。这些街道宽度标准是高住房成本和供应限制的一个因素,这些因素加剧了高成本城市的住房负担能力危机。自动驾驶汽车的规划凸显了城市街道的过度规划。因为自动露营车可以避开限制无家可归者使用街道的市政反露营限制,所以它们能够模糊住房用地和街道用地之间的区别。我提出了两种策略,通过这些策略,多余的街道空间可以以正式的方式容纳住房。首先,城市可以允许露营车在路权上停车,类似于在英国一些城市提供住房选择的运河船。其次,将私人住宅地块延伸到路权中,将为前院附属住宅单元创造空间。

Recently, there has been a renewed interest in statements about people’s rights to our streets. Drawing broadly from the literature and from an examination of a comprehensive collection of these rights, this article works toward establishing a comprehensive ethical framework that can be used to guide planning, design and engineering decisions to support pedestrian rights for street and urban livability. To identify and propose these ethical principles and help achieve optimal livability for individuals, groups and society, we: (a) comprehensively examine the literature to clarify the various concepts of street livability and human rights to the street (as related to a collection of various pedestrian rights statements); (b) explore what is being said in these rights to better understand people’s needs and wants; and (c) provide a roadmap for planners, urban designers, and engineers to address these needs in practice. Building on the previous steps and incorporating business practice literature of Functional Area Ethics, relevant functional areas are identified to help professionals act in support of these pedestrian rights.

Planning a high-frequency transfer-based bus network: How do we get there? 规划一个基于高频换乘的公交网络:我们如何到达那里?

As cities have grown more dispersed and auto-oriented, demand for travel has become increasingly difficult to meet via public transit. Public transit ridership, particularly bus ridership, has recently been on the decline in many urban areas in Canada and the United States, and many agencies have either undergone or are planning comprehensive bus network redesigns in response. While comprehensive bus network redesigns are not novel to public transit, network redesigns are commonly being considered in cities to optimize operational costs and reverse downward trends in transit ridership. For cities considering a comprehensive bus network redesign, there is currently no comprehensive easy-to-follow planning process available to guide cities through such a major undertaking. In light of that, this study presents a methodology to guide transport professionals through the planning process of a bus network redesign, using Longueuil, Quebec, as a case study. Currently, Longueuil operates a door-to-door network, and the goal is to move to a transfer-based, high-frequency service while keeping the existing number of buses constant. A variety of data sources that capture regional travel behavior and network performance are overlaid using a GIS-based grid-cell model to identify priority bus corridors. A series of analyses to measure and quantify anticipated and actual improvements from the proposed bus network redesign are conducted, including coverage analysis, change in accessibility to jobs, and travel time analysis. Accessibility to jobs was the key performance measure used in this analysis and is presented as a useful tool for planners and transit agencies to obtain buy-in for the proposed plan. This methodology provides transport professionals with a flexible and reproducible guide to consider when conducting a bus network redesign, while ensuring that such a network overhaul maximizes the number of opportunities that residents can access by transit and does not add an additional burden to an agency’s operating budget.
随着城市变得更加分散和以汽车为导向,人们的出行需求越来越难以通过公共交通来满足。在加拿大和美国的许多城市地区,公共交通乘客,特别是公共汽车乘客,最近一直在下降,许多机构已经或正在计划对公共汽车网络进行全面的重新设计。虽然对公交网络进行全面的重新设计对公共交通来说并不新鲜,但在城市中,重新设计公交网络通常是为了优化运营成本和扭转公交客流量下降的趋势。对于考虑全面重新设计公交网络的城市,目前还没有一个全面的易于遵循的规划流程来指导城市完成这项重大任务。鉴于此,本研究提出了一种方法来指导运输专业人员通过重新设计公交网络的规划过程,并以魁北克的朗格伊为例进行了研究。目前,Longueuil运营着一个门到门的网络,其目标是在保持现有公交车数量不变的情况下,转向以换乘为基础的高频服务。利用基于gis的网格单元模型,将捕获区域出行行为和网络性能的各种数据源叠加在一起,以确定优先公交走廊。我们进行了一系列分析,以衡量和量化建议的巴士网络重新设计所带来的预期和实际改善,包括覆盖分析、工作地点的可达性变化和旅行时间分析。工作的可及性是本分析中使用的关键绩效衡量标准,并作为规划人员和运输机构获得对拟议计划的支持的有用工具。这种方法为交通专业人员在进行公交网络重新设计时提供了一个灵活的、可复制的指导,同时确保这种网络大修最大限度地增加了居民乘坐公交的机会,并且不会给机构的运营预算增加额外的负担。

Land use uncertainty in transportation forecast 交通预测中的土地利用不确定性

Using an integrated land use and travel model system implemented for the Puget Sound region in Washington state, a Bayesian Melding technique is applied to represent variations in land use outcomes, and is propagated into travel choices across a multi-year agent-based simulation. A scenario is considered where zoned capacity is increased around light rail stations. Samples are drawn from the posterior distribution of households to generate travel model inputs. They allow for propagation of land use uncertainty into travel choices, which are themselves assessed for uncertainty by comparing against observed data. Resulting travel measures of zonal vehicle miles traveled (VMT) per capita and light rail station boardings indicate the importance of comparing distributions rather than point forecasts. Results suggest decreased VMT per capita in zones near light rail stations and increased boardings at certain stations with existing development, and less significant impacts around stations with lower initial development capacity. In many cases, individual point level comparisons of scenarios would lead to very different conclusions. Altogether, this finding adds to a line of work demonstrating the policy value of incorporating uncertainty in integrated models and provides a method for assessing these variations in a systematic way.
使用为华盛顿州普吉特湾地区实施的综合土地利用和出行模型系统,应用贝叶斯融合技术来表示土地利用结果的变化,并在多年基于代理的模拟中传播到出行选择中。考虑在轻轨站周围增加分区容量的情况。从家庭的后验分布中抽取样本,以生成旅行模型输入。它们允许将土地利用的不确定性传播到旅行选择中,旅行选择本身通过与观测数据进行比较来评估不确定性。由此产生的人均区域车辆行驶里程(VMT)和轻轨站乘车量的出行测量表明了比较分布而非点预测的重要性。结果表明,轻轨站附近地区的人均VMT下降,现有开发的某些车站的上车人数增加,而初始开发能力较低的车站周围的影响较小。在许多情况下,对情景进行个别点级比较会得出截然不同的结论。总之,这一发现增加了一系列工作,证明了将不确定性纳入综合模型的政策价值,并提供了一种系统评估这些变化的方法。

Investments in light rail transit (LRT) have become increasingly popular solutions to promote sustainable urban transportation. However, their impacts on cities are still subject to discussion in the academic community. There is a clear need to better understand the potential impacts of LRT projects, particularly in contexts other than major cities. In this study, we focus on the Olsztyn tram project, which has been implemented in a city of 173,000 residents situated in northeastern Poland. The paper combines different perspectives and data sources, including a study of residents’ stated preferences concerning travel behavior and modelling of housing price effects using the difference-in-differences approach. Our results suggest that the Olsztyn tram project led to a moderate change in travel behavior by increasing the frequency of public transport use but did not result in a substantial shift away from car commuting. Concerning the property market, a decline in prices was observed during the construction phase, but no statistically significant effects were found after completion.
投资轻轨交通(LRT)已成为促进可持续城市交通的越来越受欢迎的解决方案。然而,它们对城市的影响仍有待于学术界的讨论。显然需要更好地了解轻轨项目的潜在影响,特别是在大城市以外的环境中。在这项研究中,我们重点关注Olsztyn有轨电车项目,该项目已在波兰东北部一座拥有173000名居民的城市实施。该论文结合了不同的视角和数据来源,包括对居民对旅行行为的既定偏好的研究,以及使用差异中的差异方法对房价效应进行建模。我们的研究结果表明,Olsztyn有轨电车项目通过增加公共交通的使用频率,导致了出行行为的适度变化,但并没有导致从汽车通勤的实质性转变。关于房地产市场,在施工阶段观察到价格下降,但竣工后没有发现统计上的显著影响。

Cycling can be particularly beneficial for socioeconomically disadvantaged populations. First, because it can allow them to access opportunities that by other modes they may not afford. Secondly, because it can increase their physical activity levels and, consequently, improve their health. We analyse the extent to which socioeconomic disadvantage impacts on cycling participation in England, for both leisure and utility cycling. Then, we explore the extent to which this impact could be explained by the environment in which disadvantaged populations live.  The study population includes 167,178 individuals, residing in 2,931 areas, and 326 Local Authorities. Data on individual factors were drawn from the Active Lives Survey, and data on environmental factors from several sources. Descriptive statistics and multilevel logistic models were estimated. The likelihood of cycling is lower among people living in deprived areas than among people living in non-deprived areas. This difference is significant for leisure, but also for utility cycling when controlling for individual and environmental factors. The study also found that cycling infrastructure and greater levels of cyclability are higher in deprived areas than in non-deprived areas. This suggests that infrastructure and cyclability are not enough to increase cycling levels among disadvantaged populations. Further research on other barriers to cycling among disadvantaged populations is required.
骑自行车对社会经济上处于不利地位的人群尤其有益。首先,因为它可以让他们获得通过其他方式可能无法获得的机会。其次,因为它可以增加他们的身体活动水平,从而改善他们的健康。我们分析了社会经济劣势对英国自行车参与的影响程度,包括休闲和公用自行车。然后,我们探讨了这种影响在多大程度上可以用弱势群体生活的环境来解释。研究人口包括167,178人,居住在2,931个地区和326个地方当局。个人因素的数据来自积极生活调查,环境因素的数据来自多个来源。估计了描述性统计和多级逻辑模型。生活在贫困地区的人骑自行车的可能性低于生活在非贫困地区的人。这种差异在休闲方面是显著的,但在控制个人和环境因素的情况下,这种差异也适用于效用骑行。研究还发现,贫困地区的自行车基础设施和可骑行性水平高于非贫困地区。这表明基础设施和可骑行性不足以提高弱势群体的骑行水平。需要进一步研究阻碍弱势群体骑自行车的其他障碍。
